摘要： Packets are received from a network, and for each received packet, it is determined whether the packet belongs to one of a plurality of previously identified flows using a plurality of existing flow rules. For each received packet determined to belong to one of the previously identified flows, a flow identifier is assigned to the packet to indicate the previously identified flow to which the packet belongs and the packet or a packet descriptor corresponding to the packet is directed to a next location in a packet forwarding pipeline. Additionally, for each received packet determined not to belong to one of the previously identified flows, it is determined whether the packet belongs to a currently unknown flow. If a received packet is determined to belong to a currently unknown flow: the packet is sent to a processing unit associated with the packet forwarding pipeline; the packet is analyzed using the processing unit; an additional existing flow rule corresponding to the packet is determined using the processing unit; and based on the analysis of the packet; and the additional existing flow rule is added to the plurality of existing flow rules.

摘要： A switch includes a plurality of ports. A memory stores a bridge table including an entry that associates an Internet Protocol (IP) multicast destination address and an IP source address with a port indicator, which identifies one or more of the plurality of ports. When the switch receives an Ethernet packet comprising an IP multicast packet, a controller generates a key based on an IP multicast destination address and an IP source address associated with the Ethernet packet and performs a lookup on the bridge table using the key. The controller floods the Ethernet packet to the one or more ports identified by the port indicator in response to confirming that the entry is an IP multicast entry and determining that the IP multicast destination address and the IP source address of the entry matches the IP multicast destination address and the IP source address of the Ethernet packet.

摘要： A system and method of managing data packets for transmission in a virtual network are disclosed. In some implementations, a network switch may generally comprise a packet modifier that modifies a VLAN tag state of a packet to be egressed as a function of an egress interface and a VLAN-ID assignment. The modified VLAN tag state may include one or more VLAN tags that are in a different order, or that have a different content, in comparison to the VLAN tags of the packet at the time of ingress.
